Our civils design is undertaken using Civils 3D and integrated with the structural model using Navisworks.

CADS-RC is used for the 2D detailing of reinforcement, which generates automated bending schedules; we are considering implementing 3D reinforcement detailing although at present we are awaiting advancements in the currently available software before making this transition.

PTA operate a Windows network with appropriate anti-virus protection, with workstation PCs that are of a specification to handle the software demands on it, and are subject to upgrade as and when their performance is outdated by the operating requirements of the latest version of the software being used. All project data is backed up to an external source, on a regular basis to ensure there is a disaster recovery system available.

BACKGROUND / BIM EXPERIENCE

Our use of 3D modelling software started in 2012 and during this year Revit was implemented as the default process for all of our projects. Since then we have gained experience of working at BIM Level 2 of the PAS 1192-2 Maturity Index, collaborating with Design Team members to produce integrated BIM models that have been fully coordinated through a strictly controlled clash detection process using Navisworks. Operating at BIM Level 2 has not impacted on contractual or PI implications, since traditional responsibilities are maintained at this level.

Often we are the sole member of the Design Team using 3D BIM on projects for private developers; however, more frequently we are finding that the M&E Consultant/Façade Consultant/Contractor is using 3D BIM and benefitting from our structural model, whether as Revit ‘.rvt’ files or ‘.IFC’ files.

We anticipate that BIM Level 2 will become more commonplace on private developments in the future and our technical capabilities are now well-positioned for this. BIM is now fully integrated into our design process and we are fully committed to maintaining and developing our capabilities as the use of BIM within the construction industry continues to evolve.

BIM MANAGEMENT STRUCTURE

We have a team of advanced Revit Technicians led by a designated CAD Management Team (CMT) and CMT Liaison Director who are responsible for BIM Policy and implementation.

BIM TRAINING

The technical training of our team is kept up-to-date through a combination of external training for major software updates complimented with internal seminars/best practice working protocols led by the CMT.

BIM Management training is by means of external training and internal seminars.

INFORMATION MANAGEMENT / COLLABORATION

All of our BIM Level 2 projects are allocated a designated BIM Manager to control the exchange of coordination models and manage clash detection exercises.

We also utilise a dedicated Document Controller for administering our information exchange with the Client’s designated Common Data Environment and we are familiar with the use of Aconex, Sharepoint, Data Q, etc.
